Difference between Phasor Simulation and Load Flow

I am modeling two area power system in Simulink for which I am able to successfully run load/power flow using Powergui - Load Flow Tab. But when I run the Phasor simulation of the model it throws error as:

"There is no voltage source, current source, or machine block with a frequency matching the Phasor simulation frequency."

In the two area system there are only generators, loads, lines and shunts. I am trying to understand the difference between load flow and Phasor Simulation?

Hello Puneet,

I understand that you want to understand more about phasor simulation. I have pulled up some docs that might help you:

1. https://www.mathworks.com/matlabcentral/answers/159942-can-i-use-phasor-simulation-mode-to-simulate-power-systems-with-frequency-dynamics?s_tid=srchtitle

2. http://www.mathworks.com/help/physmod/sps/powersys/ug/introducing-the-phasor-simulation-method.html 3. https://www.mathworks.com/help/physmod/sps/powersys/ug/_f12-6010.html

(Please refer to examples in the above link).

4. This explains the difference: https://electronics.stackexchange.com/questions/167533/phasor-simulation-versus-power-flow

5. I found a webinar as well:
